1) square silicon ingot
正方形截面硅晶锭
4) long square-section tunnel
正方形截面长隧道
1.
Based on the theory of explosion mechanics and by means of the ANSYS/LS-DYNA software,the present paper sets a numerical analysis for the distribution law of overpressure on walls induced by an explosion in long square-section tunnel.
以爆炸力学为理论基础,利用有限元软件ANSYS/LS-DYNA,定性地研究了正方形截面长隧道内爆炸引起的内壁上超压分布规律。
5) multi-crystal silicon ingot
多晶硅锭
1.
The content of oxygen,carbon and metal impurities in the remelted material was analyzed so as to find out if the pot material could be used as the feedstock to produce multi-crystal silicon ingot for solar cell.
试验发现通过重熔可以将单晶硅埚底料中的石英与硅料分离,重熔后得到的硅片中氧含量比较高,而金属杂质含量基本可达到太阳电池多晶硅锭的生产要求。
6) silicon ingot
硅单晶锭
1.
This paper introduces one measuring method for the silicon ingot based on the X-ray diffraction principle,and the measuring model was set up simultaneous.
本文介绍了一种基于X射线衍射原理的半导体材料—硅单晶锭的加工测量方法,建立了硅单晶锭的测量模型。
